Kubernetes support

[Chriscbr]

Feature Spec

Provide ways to define Kubernetes services in Wing applications.

Here's a sketch based on our conversations yesterday (all is subject to change):

bring cloud;
bring k8s; // <-- cdk8s-plus behind the scenes?

class MyMicroService extends cloud.Kubernetes {
  init() {
    let d = new k8s.Deployment(replicas: 2);

    d.addContainer(
      image: "paulbouwer/hello-kubernetes:1",
      portNumber: 8080
    );

    let s = d.exposeViaService();

    let ingress = new k8s.Ingress();
    ingress.addRule("/my_service", k8s.IngressBackend.fromService(s));
  }
}

new MyMicroService();

• When compiled to sim, this uses a local k8s cluster such as kind, MiniKube, k3s or Docker Kubernetes (do we need the user to install this or do we bundle this with wing somehow?).
• When compiled to tf-aws, this creates a singleton EKS cluster (or allows the user to specify).

Use Cases

Build Kubernetes based applications: define the resources within the cluster.

Out of scope: define the cluster infrastructure itself.
